It also fits the Argus LCM and several additional Schiller medical devices that share the same OEM cell spec. Voltage and capacity match the NP2.3-12FR \/ B10665 \/ 0997-00-0262 original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePT-160 and DEFIGARD 4000 platform compatibility:\u003c\/strong\u003e\n    Both devices run the same 12V sealed lead-acid rail with identical connector and BMS handshake requirements. The shared cell format across this platform means one replacement cell covers the PT-160, DEFIGARD 4000, and Argus LCM without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, hold, and load discharge on the PT-160 platform. The BMS accepted the cell on first insertion, completed charge without flagging a fault, and delivered stable voltage through simulated defibrillator load draws.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the device to complete its full power-on self-test without interruption. Schiller defibrillators run a BMS verification sequence at startup — cutting power mid-cycle triggers a false battery fault that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the PT-160 flags a battery fault after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PT-160's charge IC applies a conservative acceptance threshold calibrated to a broken-in OEM cell. A fresh sealed lead-acid cell has slightly higher internal resistance than a conditioned one, which can push the measured voltage just below the device's pass threshold on the first cycle. This does not mean the cell is faulty. Run one full charge-discharge cycle before treating any fault indicator as genuine. After that cycle, internal resistance drops and the device BMS reads the cell as within spec.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSealed lead-acid cells self-discharge over time, and if voltage drops below approximately 10.5V, the Schiller BMS enters a protection state and refuses to boot. The fix is a slow pre-charge: connect to a compatible SLA charger set to 12V trickle mode and leave it for at least four hours before attempting power-on. Once cell voltage recovers above 11V, the BMS releases and the device boots normally. Do not attempt a fast charge on a deeply discharged SLA cell — it stresses the plates and may trigger a permanent fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381389492314,"sku":"BWCS-SHT160MD-1","price":310.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381389525082,"sku":"BWCS-SHT160MD-2","price":370.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381389557850,"sku":"BWCS-SHT160MD-3","price":415.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHT160MD-1.webp?v=1778900511","url":"https:\/\/batteryweb.com\/products\/schiller-pt-160-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
